Wow, I gotta say that though this stuff is a bit above and beyond my simple knowlege, I have to say I find this stuff very interesting. I have no idea what interlacing is so I hope you can give me the "explanation for dummies". The material I upload is taken from old vhs copies I have in my collection that I've transferred to dvd-r, then I convert it to DivX with DivX Author. Billbarstad has often noted in his reviews of my uploads the video quality, good, bad, or otherwise. The fact is, when he noted on one upload that the video quality was poor, truth to tell, I wasn't too crazy about it either. The source material wasn't that great to begin with. I only know how to upload the source material. If I knew a way to improve on it, I'd go for it. I sure would like to learn more about converting video files as I know I'm far from being an expert.

guyzilla:

I, for one, appreciate your honesty in admitting that you are confused about how to make sure that your uploads are of the best quality that you could possibly do. As a lot of the videos here at IA demonstrate, many do not care. They just want to be the "first" to haphazardly put something up and are not concerned with quality. Others have a "Let them eat cake!" mentality and just want to throw the menial masses some crumbs. It's refreshing to see that Scott Saunders does not fall into either of those categories. You can tell that he actually cares about the quality of his uploads. (Even though I'm not a big fan of MP4's.)

As Scott says, the processes involved in creating a good quality video are complicated. However, it's not impossible if one takes the time to do a little research beforehand.

Many years ago, I started reading at a website now called videohelp.com (back then they were vcdhelp.com). They have some great, in depth, step-by-step, tutorials on ripping, capturing, and converting video using a wide variety of different software and hardware. You will find that a lot of it is trial and error. Sometimes the software and/or the hardware gets it wrong. It's important that you be able to spot this and try something different.

Good luck and looking forward to great videos from you.

Thanks for the info. I'll be trying my first upload soon. Wish me luck.

A late response, but I just saw your post:

I hope that you realize when I review any movie here - not just yours, what I say about video quality is meant to let people know what to expect before they download. I make a point not to criticize the contributor, unlike some reviewers. Those of us who post movies here are making a selfless act and, generally speaking, do the best we can with the materials and software we have. And, yeah, video encoding has a learning curve. Took me many months to get good at it, but I wasn't doing it that often, either. I've re-uploaded movies to provide better quality after having learned more. I wish I had the time and bandwidth to re-encode and re-upload some others. I'm glad you have been able to contribute movies (especially the hilarious 'The Eye Creatures' - oh yes, I said it!), and I hope you can continue to contribute.

I'm guessing that you use a Windows machine, so I can't help you with tips and the like.

Interlacing was created to display video on CRTs and minimize the number of frames broadcast. Interlacing refers to a common method for painting a video image on a display by displaying each line or row of pixels. This technique uses two fields to create a frame. One field contains all the odd lines in the image, the other contains all the even lines of the image. what you get when you rip a interlaced movie is horizontal lines appearing in the video, especially noticeable during motion. I use a program that allows for de-interlacing, which slows encoding. You don't always know if your source material is interlaced, so it's trial and error or always choosing de-interlacing during encoding.

Dual pass encoding is great for getting high video quality at a lower (1500kbps or below) bitrate. A lower bitrate often yields a smaller file.

The H-264 MPEG4 video codec is, in my opinion, currently the best for quality and small size, but requires more computing power, thus taking longer that other MPEG4 codecs.

An even later response,

so if I may inquire,

what tools do you use to De-Interlace and Duel Pass Encode

Thanks - Bill

I use the Mac program Handbrake mostly. I don't deinterlace; I inverse telecine when necessary. You can do 1- or 2-pass encoding with it.
